METHOD OF MAKING BARRELS, 80o.

SPECIFICATION forming part of Letters Patent No. 479,734, dated July 26, 1892.

Application filed January 28, 1892. Serial No. 419,598. (No model.)

To all whom it may concern; 410,206, filed October 29, 1891, or preferably Beitknown that I, HENRY CAMPBELL, a citiby that set forth in my application filed Febzen of the United States, residing at Baltimore ruary 8, 1892, Serial No. 420,773, in which the city, in the State of Maryland, have invented setting up and firing are performed simultane- 5 certain new and useful Improvements in ously; but this operation is not necessarily 55 Method of Making Barrels, &c.; and I do deconfined to the use of these particular formers clare the following to be afull, clear, and exact or setting-up machines. description of the invention, such as will en- In the accompanying drawings, Figure 1 is able others skilled in the art to which it appera face View of a barrel-stave crozed and ready I tains to make and use the same, reference befor the setting-up operation.

Having thus described my invention, What I claim is V 1. The herein-described method of making barrels and similar articles, which consists in first crozing the staves individually or when uncombined permanently in the barrel, then setting up the staves around one of the heads of the barrel and forming the latter, then applying permanently the hoops to that end of the barrel containing said head, then, the partly-finished barrel having been fired,forcing in the stares at the other end of the barre], the other head being at the same time inserted, then applying the head-hoop to secure the last-mentioned head, and applying the remaining hoops, substantially as set forth.

2. The herein-described method of making barrels and similar articles, which consists in first crozing the staves individually or when uncombined in the barrel, then setting up the staves around one of the heads of the barrel and forming the latter and simultaneously firing the barrel, then applying permanently the hoops to that end of the barrel containing said head, then forcing in the staves at the other end of the barrel, the other head being at the same time inserted, then applying the head-hoop to secure the last-mentioned head, and lastly applying the remaining hoops, substantially as set forth.

3. The herein-described method of making barrels and similar articles, which consists in first crozing the staves individually or when uncombined in the barrel, then consecutively setting up a seriesot' barrels, applying to each one or more of its permanent hoops, and beginning the firing of each barrel when its setting up is begun, and then consecutively windlassing and finishing said barrels, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY CAMPBELL.
